ABSTRACT:
A dispenser of the type using a threaded rod with a turning knob is applied to a disposable cartridge and plunger. The cartridge plunger has a threaded central sleeve that is sealed closed, and the threaded rod, knob, and an anchorage adapter are separate from the cartridge until dispensing is to begin. Then the rod is threaded through the sleeve to puncture the seal and advance through the material to bring the anchorage adapter adjacent the rear end of the cartridge. The anchorage adapter is then releasably secured to the rear end of the cartridge, and the rod turned in the opposite direction to advance the plunger for dispensing material. The plunger can be backed up to stop drool if dispensing is interrupted, and the rod, knob, and adapter can be removed and reused after dispensing is completed.
